The Wow: "This is a great life changing surgery when it is truly needed," one woman writes. Others title their reviews "the best decision I've ever made in a life" and "no more batwings!" This procedure has been a great self-esteem boost for women who were feeling uncomfortable in their new skin following dramatic weight loss. "I do love my new skinny girl arms!" one woman raves.

The Ow: "My hands looked like little sausages after surgery," one woman writes, summarizing the most traumatizing part of her experience. This procedure has one of the shorter recovery times, but it can get ugly. "The worst thing was that I had some sutures come out of my elbows, about a month and a half into recovery. I took two weeks off of work. For about one week I walked around like a mummy, two weeks I mostly had swelling at the end of the day, and at three weeks I could lift my arms over my head." Another woman got more bang for her buck: "My surgeon lifted the skin that would be what would bulge over the back of the bra and in doing so he went into my armpit. I will now not have to worry about shaving under the pits ever again! Bonus! But...I don't have a "traditional" arm pit now." You win some, you lose some.
